Title: Hvac distribution system identification
Inventor: AHMED OSMAN
IPC: F24F11/00
Filed: 1995-10-03
Granted: 1999-04-13
Abstract: A controller implemented in a heating, ventilation and air-conditioning (HVAC) distribution system provides improved control by implementing a general regression neural network to generate a control signal based on identified characteristics of components utilized within the HVAC system. The general regression neural network utilizes past characteristics and desired (calculated) characteristics to generate an output control signal. The general regression neural network is implemented in a feedforward process, which is combined with a feedback process to generate an improved control signal to control components within the HVAC distribution system. Implementation of the general regression neural network is simple and accurate, requires no input from an operator supervising the controller, and provides adaptive, real-time control of components within the HVAC distribution system.

Title: Aspartoacylase gene, protein, and methods of screening for mutations associated with canavan disease
Inventor: MATALON REUBEN
IPC: C12Q1/6883
Filed: 1994-07-05
Granted: 2007-09-11
Abstract: Canavan disease, an autosomal recessive leukodystrophy, is caused by deficiency of aspartoacylase and accumulation of N-acetylaspartic acid in brain. Human aspartoacylase (ASP) cDNA spanning 1,435 bp has been cloned and expressed in E. coli. A base change, a854>c, has been found in 85% of the 34 Canavan alleles tested so far, which results in a missense glu285>ala mutation that is predicted to be part of the catalytic domain of aspartoacylase. Several additional mutations have also been identified. The invention therefore provides nucleic acid sequences, genes, polypeptides, antibodies, vectors containing the gene, host cells transformed with vectors containing the gene, animal models for the disease, methods for expressing the polypeptide, genetic screening methods and kits, diagnostic methods and kits, methods of treating Canavan disease and methods of genetic therapy for the disease.

Abstract: Configuration de pastille (40) de brasage non obturante ominidirectionnelle destinée à des plaquettes (10) de circuits imprimés, cette configuration comprenant une pluralité de bras (42) rayonnant vers l'extérieur depuis un trou traversant (16) formé sur la plaquette (10) de circuits imprimés, un anneau (44) concentrique par rapport au trou traversant entrecoupant chacun des bras approximativement à un angle perpendiculaire. Grâce à cette configuration à bras rayonnants et anneau, il devient inutile de s'assurer que la pastille de brasage est bien orientée sur la plaquette (10) de circuits imprimés avant d'effectuer le procédé de brasage tendre à la vague, étant donné que la configuration à anneaux symétriques et à bras est omnidirectionnelle. La structure annulaire concentrique produit une surface de contact supplémentaire de brasage entre la plaquette de circuits imprimés et un boîtier (12) d'ordinateur. Cette surface de contact supplémentaire de brasage assure qu'il existe suffisamment de connexions électriques entre la plaquette (10) de circuits imprimés et le boîtier (12) d'ordinateur de sorte que, lorsque la plaquette (10) de circuits imprimés est montée sur le boîtier (12) d'ordinateur, il s'établit une connexion à la masse appropriée.

Abstract: In an apparatus for receiving a series of loops descending along a vertical path from the delivery end of a conveyor and for accumulating the thus received loops into an annular coil, a device for horizontally distributing the descending loops. The device includes a ring surrounding the vertical path. The ring has a cylindrical vertical wall and a radially outwardly extending horizontal ledge. A curved guide member extends around a segment of the ring and has leading and trailing ends. The guide member protrudes inwardly from the ring into the vertical path, with the extent of the inward protrusion being greater at the trailing end than at the leading end. The guide member is in mechanical interengagement with the horizontal ledge and in horizontal abutting engagement with the vertical wall to thereby accommodate vertical placement and removal of the guide member onto and off of the ring without attendant radial displacement of the guide member with respect to the ring.

Title: Teleworking arrangements
Inventor: BOOTON LAURENCE JON
IPC: H04M7/12
Filed: 1996-03-27
Granted: 2000-08-22
Abstract: In a known automatic call distribution (ACD) suite comprising a PABX (10) and an associated ACD system (12), and limited to managing a work force of local agents, the ACD system distributes incoming external calls to a plurality of internal terminals (22) of the PABX (10) according to a predetermined set of rules. A teleworking facility is provided with a Computer/Telephony Integration controller (26) connected to the PABX and arranged to select an available one of a set (34) of the terminals (22) designated as "dummy" terminals, to receive the identity of a teleworking agent requesting work (or select the identity of a teleworking agent to be offered work), and to command the ACD system to record the teleworking agent's identity in association with the identity of the selected dummy terminal.  When the controller detects that the ACD system has connected an incoming call to the selected dummy terminal, it commands the PABX to make an outgoing external call to the teleworking agent at the recorded remote terminal (36) and to join the two calls in conference mode.  The call to the dummy terminal can be answered and put on hold until the teleworking agent answers and then joined, or it can be answered after the teleworking agent answers and then joined.  The CTI controller can be arranged to initiate calls in a telesales mode.  All working calls involving the teleworking agent originate at the call centre.  Furthermore, the ACD system is commanded to record a teleworking agent's identity in association with a terminal identity, and in this way the ACD system will include the teleworking agent in its statistics measurements as if that teleworking agent were a local agent, and only the controller "knows" that the agent is a teleworking agent and that the terminal is a dummy terminal.

Abstract: The invention relates to an apparatus for aerating a ground layer, comprising:   - a frame movable along a ground surface, - a number of substantially vertically placed aerating pins movable in and out of the ground layer, - each pin being engaged by a pivot arm mounted on the frame for pivoting, and - a guide arm connected to the frame at a distance from the position where the pivot arm engages said frame, - drive means for causing reciprocal pivoting of the pivot arm during the movement of the apparatus along the ground layer.      The connections of the pivot arm to the frame and the aerating pin and the connections of the guide arm to the frame and the aerating pin substantially form corners of a parallelogram in the non-loaded state of the aerating pin. At least one of the sides of this parallelogram is changeable in length counter to biasing means, such that the bottom part of the pin is displaced relative to the top part of the pin in a direction opposed to the direction of movement of the frame; and all pivot arms and guide arms engage the frame by means of a central engaging member, the position of which is adjustable relative to the frame.

Abstract: In accordance with the present invention there is provided a novel cigarette packaging system for "making your own" smokeable cigarettes. The kit is easily opened and allows a smoker to assemble a smokeable cigarette quickly without requiring great effort. The kit is inexpensive, convenient to use and also convenient to carry and store as its compact size is such that it fits in a person's hand, a shirt or coat pocket as well as in a ladies bag or purse. The kit is also advantageous because it is less expensive than tailor made cigarettes, yet is not that much wider than a standard, typical package of cigarettes. The construction of the kit, is such that it keeps the unsmokeable tobacco elements in a separate compartment which serves to help maintain the freshness of the tobacco.
